What are NSEI and PSEI? What is their relationship? What is the connection with PCU?

1, NSEI identifies a BSC in the GPRS network.

2.PCU is the unit that BSC handles GPRS.

3.NSEI network service entity number and PCU packet service processing unit

4.NSEI is the identity of the network service entity, and Chinese literal translation is the identity of the network service entity.

NS (Network Service) is the Layer 2 protocol of Gb interface. In the current network, one SGSN connects multiple PCUs, and one PCU can only connect one SGSN, so the Gb interface is a tree topology. However, both SGSN and PCU are NSE(NS entity). In order to distinguish different PCUs connected to the same SGSN, we assign a NSEI to each PCU.

5. Turn off GENA first, then replace nsei with the next one, and then turn GENA on.

BCSU is the CPU of BSC, and PCU is the module responsible for processing GPRS on BSC.

NESI is the number of PCU;

6. PSEI: Packet Service Entity Identifier
